burette, also spelled buret, laboratory apparatus used in quantitative chemical analysis to measure the volume of a liquid or a gas. It consists of a graduated glass tube with a stopcock (turning plug, or spigot) at one end.

What is the function of a burette?

Burette is a laboratory apparatus commonly used to dispense and measure variable amounts of liquid or sometimes gas within chemical and industrial testing specially for the titration process in volumetric analysis. Burettes can be specified according to their volume, resolution, and accuracy of dispensing.

Why are Burets used for titration?

Glassware - Burets. A buret is used to deliver solution in precisely-measured, variable volumes. Burets are used primarily for titration, to deliver one reactant until the precise end point of the reaction is reached. To fill a buret, close the stopcock at the bottom and use a funnel.
